The best way to go confronting all types of fundamentalism and extremism is to educate oneself on the way that the group that you face thinks. Reading the Quran, Learning why they do what they do or learning about their culture can help open your eyes to how they think and why. Sometimes showing interest can help open doors in doing something about what’s happening. Another way to confront fundamentalism would be to stay up to date on what is happening with whatever group. This is will keep knowledgeable on what they are doing and allow you to talk and discuss it with others. Another way to confront extremism is to spread awareness in a positive manner, so to not be offensive but, be constructive. The last thing you can do is to not spread negativity about that particular group, it’s unnecessary and will help improve your outlook on them.
If we want to criticize what is evil in religious fundamentalism, the ideal perspective on the world we should encourage to approach life with is unclear. The only thing I would say is, it should be a peaceful, loving, and considerate of others. That’s all. Considerate of of others is a must if they wish to build bridges. Being kind to others is right. Fellow humans. that’s all.
